:aneunarrne VALVE.

Application filed. October 22, 19275. Serial No. 64,107.

To all wlw/m t may concern.' 'Y Be it known that we, EvAN Jones and WILLIAM R. -MCKRELL, citizens of the United States, and residents of `Pittsburgh Ei and Avalon, respectivelyfinthe county of .zgAllegheny and State of Pennsylvania, have invented certain new. and useful lmprovements inRegulating Valves, of which the followingis a specification. l

This invention relates to valves and more aparticularly tofvalves especially adapted i for use .in ,the intake manifold of internal combustion engines of automobiles and has for. its object the', provision of such a valve which may be operated from, the drivers f5 seat o f an automobile to control the flow of' explosive mixtureifrom the carburetor to the engine, and permit a regulatable supply of air tol enter they manifold. Y Anotherobject is to provide a valveof 'xfthisclass which may be .used toV completely stop the flow of the explosivemix'ture from the carburetorv to the engine when coasting downgrades with the engine acting as a brake. y

' A still further object ,is toprovide a valve having the Ynovel construction, design and combination 4of parts hereinafter described and illustrated in the accompanying drawings.

In the drawings :e v

F'gurev 1 Ais a lside'elevation'of an internal combustion engine of an automobile of standard design having the invention applied thereto.

Figure 2 is a sectional view through the valve of this invention. i

Figure 3 is a plan view thereof.

Figure 4 is a side elevationthereof.

Figure 5 is a perspective view of the valve plate.

Figures 6 and 7 are sectional views of a slightly modified form of valve.

Figure 8 is an elevation showing the valve mounted vertically between a carburetor and engine manifold.

Referring more particularly to the drawings, the letter A designates an internal combustion engine, of a well known design, which is provided with the usual intake manifold 2 and carburetor 8. The intake manifold 2 is provided with` the usual attaching flange 4 adapted to normally abut similar fla-nge or yshoulder 5 on the car-4 buretor 3, and the carburetor is secured in place by bolts 6 which pass through the flanges 4 and 5.

The regulating valve AB of this invention is mounted between the fianges 4 and 5 of the manifold and carburetor and is secured in place by the bolts 6.

The valve B comprises a 'dat relatively thin body portion 7 having a centrally disposed circular opening 8 therethrough to permit the passage of the explosive mixture from the carburetor into the manifold. rlh'e body portion 7 is also provided with an elongated rectangular slot 94 in which a valve plate 10 is mounted for sliding movement. n k.

The valve plate 10 is provided with an opening 11 equal in size with the opening 8 in the body portion 7 of the valve and adapted to be alined with the opening, 8 when the valve is in openposition.

The valve plate lOvis 4also provided with a cut-off portion 12 adapted to be'moved into position across the opening 8 to stop the passage of explosive mixture from the carburetor into the manifold and motor.

-The portion 12 is provided with a recess or depression 14 in its upper face which permits air to be drawn into the intake manifold 2 when the valve plate 10 is positioned with the portion 12 across the opening 8. The-depression 14 may be of the same depth throughoutor may be of constantly increased depth toward the forward end as shown in Figures 6 and 7. The inner end of the depression 14 is rounded or curved and the outer end is open. The rounded orv curved inner end of the depression 14 permits a fine adjustment of the air volume entering through the valve so that the leaning of the explosive mixture to the engine may be better controlled.

The valve plate 10 is adapted to be reciprocated by a wire or other flexible element 16 which is connected at 17 to the valve plate and passes through a suitable guide tube 18 to the dash 19 of the machine and terminates in a suitable hand hold 20. It will be understood that various operating means may be' used to reciprocate the valve plate and that the means shown is only illustrative.

The valve plate 10 may be adjusted to various positions se that air and an explo- Sire mixture may 'both be drawn int@ .the

manifold 2 or so that air or an explosive mixture alone may be dra-wn into the manifold.

When the engine is running at a good speed a materially leaner mixture of air and gas may be used as an explosive mixture than when starting or running slow. Therefore the valve plate 10 may be moved into position to partly close the opening 8 and move the rear end of the recess 14 into communication with the opening. This Will permit air to be drawn into the manifold and less explosive mixture so that a lean mixture is provided for the engine. This operation of the valve alone Willmatei'ially reduce gasoline consumption in an automobile.

If'the automobile is coasting down a grade With the engine acting as a brake the valve plate 10 is completely closed so that air alone is drawn through the intake. This operation Will cause a great saving in gasoline, cool the motor and cause a more efficient braking action of the engine.

While We have shown and described one specific embodiment of our invention, We do not Wish to be limited thereto, since various modifications in design, construction and combination of parts may be made Without departing from the scope of our invention as defined in the appended claims.

We claim- 1. The combination with an internal combustion engine having an intake manifold of circular cross section and carburetor, of a thin relatively flat valve body mounted between and having a circularport connect-- ing said manifold and carburetor, and a. thin relatively flat valve plate mounted'in a suitable guide opening in said body for a transverse sliding movement, said valve plate being provided with an opening adaptedto permit unobstructed passage of the explosive mixture from said carburetor through said manifold, and a cut-olf portion adapted to be moved across said vvalve port to regulate or cut-off the flow of explosive mixture to said manifold, said cut-off portion of said valve plate beingprovided with a depression adapted to permit the entrance of air to said manifold When said cut-off portion is moved across said valve port, said depression having a rounded inner end so as to permit a relatively fine adjustment of the quant-ity of air admitted to said manifold when regulating the flow of explosive mixture through said manifold.

2. The combination With an internal combustion engine having an intake manifold of circular cross section and carbureter, of a thin relatively flat valve body mounted between and having a circular port connecting said manifold and carbureter, and a` thin relatively fiat valve plate mounted `in a suitable guide opening in said body for a transverse sliding movement, said valve plate being provided with an opening adapted to permit unobstructed passage or the explosive mixture from said carbureter through said mainfold, and a cut-off `portion adapted to be moved across said valve port 'to regulate and entirely cut-off the flow of explosive mixture from said carbureter to said manifold, said cut-off portion of said valve plate being provided with a. depression having a rounded inner end and open outer end, said depression having a continually increasing cross section from said rounded inner end to its open outer end so as to provide an increasing supply of air to said manifold as said cut-off portion of said valve plate is moved across said valve port.

In testimony whereof, We have hereunto signed our names.
